Here is Part 7 of the live ABC News Viewpoint special on "The Nuclear Dilemma". This aired after The Day After on WLS Channel 7 - an ABC Theater telemovie about the effects of a full-scale nuclear attack on the United States. Hosted by Ted Koppel.

In this part [starting at 05:11] Carl Sagan gives his now famous analogy, "Imagine, a room, awash in gasoline. And there are two implacable enemies in that room. One of them has 9,000 matches. The other has 7,000 matches. Each of them is concerned about who's ahead, who's stronger..."

Christopher Michael offers two tales about a common radio mental hiccup - "At WYEN in Des Plaines, Illinois where I was an overnight jock, several of us were talking about Chicago's WCFL, and wouldn't you know, a song ended, I opened the mic and proudly said 'WCFL...' Then I paused for what must have seemed like an eternity while I tried to figure out just what the heck I would do next. I think I said something like "Well, actually, no, this is WYEN. But you knew that." We were known as Request Radio, but one night I was listening to WLS, 'the Big 89,' on my way to work and was really connected to the music and J.J. Jeffries doing the evening show. So I got on the air and with my first selling of the phone number for requests, I gave the phone number for WLS. We were a suburban Chicago station with a fairly low number of listeners - or so I thought. I learned otherwise when people started calling me, saying the guy at the phone number I gave was getting really angry that our listeners were calling him!" Christopher went on to work for Mutual, NBC, was an editor and writer for Paul Harvey - and is now a news anchor at WLS.
